Abstract. Structure from motion (SfM) has seen rapid uptake recently in the fluvial sedimentology. This uptake is not least due to the widespread availability of cheap unmanned aerial vehicles/drones, which help mitigate the challenging terrain and deliver efficient and reproducible and high-accuracy images and topographical data. The current study describes the application of SfM in order to build a geomorphological model and estimates surface water velocity of Way Semaka River in BNS region, West Lampung. Way Semaka river is river type with a large meandering system and stable extension tectonic regime, relatively. River morphology approximately 96.62 m width and 4 m depth in straight (relatively) area, whereas in channel area approximately 171.22 m width and 5 m depth. The velocity range between 0.39 – 1.56 m/s based on image analysis and proven by current meter measurements onsite with an RMS error 0.25. Manual geomorphic unit level 2 analysis revealed that for the zone within the channel, 9% of the coverage consisted of basins, 35% of the coverage consisted of convexity, 9% consisted of planar features and 37% of the coverage consisted of the transition zone
